Question for Those who know how to Growl

[Gsoul82]

So, I finally have a technique question. I saw a video about grunting and I essentially was able to work it into a growl that I can apply to singing. I can consistently do this now, but I know this can be harmful if done wrong, so I was wondering, to those who believe they are doing this right, and can consistently do this and have never had any problems, how does it feel to you? I've experimented with it, but not used it a whole ton. I've gotten it to the point where I barely feel it very little, if at all. Just looking for experiences to compare it to.
